By the 24nd century, CPR and defibrillation had been rendered obsolete in favor of strong cardio-stimulant and neuro-stimulant drugs and the cortical stimulator. Although it is a possible conjecture that a defibrillator was used on Sarek during his surgery in TOS: "Journey to Babel", this judgment cannot be made definitively.

While not common, it was never said that it was obsolete. The second sentence is speculation.--31dot 14:02, 11 April 2009 (UTC)
